MU: good question. I guess I mean when I click on a wiki concept, like say "Bob" and now I'm on Bob's page. Or I might be on the page for the wiki concept: Idaho. -- Is it just a place to hold an exchange of information (analogous to a "thread" in a forum)? If so, what does it mean to attach an attribution (a triple) to this page - should I interpret that all triples have the page as subject, which is a resource in some sense, and the meaning is whatever you assign to these triples? MU: this is what Semantic Media Wiki assumes, as I understand it. That is why in the triples in the markup, you don't have the subject explicitly there, it is assumed. In which case the page only really has doubles there explicitly, not triples. This assumption makes it impossible to add a real triple that relates to something else. -- Is it supposed to encapsulate some kind of concept or set of concepts - then the triples be interpreted as statements about these concepts? Must it be in some sense "self-contained" - relative to some discourse, or relative to some conceptualization schema? I'd be very interested in knowing more the requirements (and scenarios) you seem to have in mind when you state that "that's why I stopped trying to use the tool"... what kind of applicaton do you need? MU: I want to create a wiki page, classify that page as being an instance of some class. So say I create a page for Bob, he is an instance of Person. On that page, I want to be able to write unstructured text. Like Bob lives in Idaho. And to be able to create a triple that says that. And I also mention Montana in the text, and while I'm thinking about it, Idaho borders on Montana. So from the web page, I want to be able to create Idaho and Montana as wiki concepts. Then I want to select each of them, and then choose among a set of relationships which includes bordersOn and set that relationship between these two concepts. Now I have a triple. I don't care where it is stored, it can be associate with any page or no page. In fact I don't even want to see it. I want the tool to take care of all that for me. Furthermore, the system now should know that Idaho and Montana are say, regions from the domain and range constraints of bordersOn**. ** Lets ignore the fact that a state is a political entity, and has an associated region. That's an ontology issue, not a tool issue. Cheers, Daniel --- Daniel Schwabe Dept. de Informatica, PUC-Rio Tel:+55-21-3527 1500 r. 4356 R. M. de S.
